During operation, condensate is both produced in the heater and collected from the vent-
ing system. Therefore, the installaton requires a condensate drain from the secondary heat 
exchanger and a condensate drain from the 

fl

 ue exhaust pipe.   A short 

fl

 ue pipe with 3/4” 

condensate drain point is supplied with the heater and a  PVC collar for PVC tube of dia 32 
is provided to drain the condensate from the secondary heat exchanger (see 

fi

 gure 5).

Important : each condensate drain must include a separate trap (no part of delivery).
